Abstract
A voltage regulating system for a diode-rectified alternating current generator that supplies the electrical loads on a motor vehicle including charging the storage battery. The voltage regulator has a reference voltage developing circuit that can operate either in a temperature compensated mode or a flat mode. In the temperature compensated mode the reference voltage developed by the circuit varies with temperature and while the circuit is in the flat mode the reference voltage remains substantially constant with changes in temperature. The voltage regulator has a switching transistor connected in series with the field winding of the generator which can operate in a current limiting mode in the event that sensed field current becomes excessive. The voltage regulator includes circuitry for ensuring that the output voltage of the generator properly builds-up when the field winding is initially excited by the battery.
